    Aug 30, 2018 · So, when we start the compressor, power is applied to V1 (or to V), and once oil pressure builds up to the 9-12 PSIG range, it will open switch PC and de-energize the heater. Now, if this switch (PC) is closed, and the control is energized (power to V1 or V2), then heater H is energized. Once that heater reaches a certain temperature, switch TD

  • HPHT: completions, challenges, and coping with the pressure

    Mar 11, 2019 · The term HPHT is typically used to describe high-temperature, high-pressure wells that are at either a higher temperature or pressure than most other oil wells – usually over 150°C and 10,000psi at their deepest point. If a well exhibits these characteristics, it is likely to pose greater challenges when drilling.

    Mistake No. 3 – Running too hot. Few equipment owners or operators continue to operate an engine that is overheating. Unfortunately, the same cannot be said when the hydraulic system gets too hot. But like an engine, the fastest way to destroy hydraulic components, seals, hoses and the oil itself is high-temperature operation.
